One of the great heritage walks in Hong Kong, Ping Shan wends its way through traditional Tang clan villages in Yuen Long, past Hang Mei Tsuen, Sheung Cheung Wai and more. Some sites date back as far as the 14th and 16th centuries (ancestral halls and pagodas) and provide an eye-opening glimpse into Hong Kong’s past. Among the highlights are the 19th century police station (now serving as a museum) and the stunning modern library at the end of the trail.
